So I have a turbo from a 6.0l that I want to put on my idi. Obviously the turbo is a vgt of sorts, so I'm wondering whether or not I should just remove all the vanes and unison ring or see if I can rig up some sort of controller for the solenoid. Has anyone ever tried this? This turbo looks huge on this truck. I will be making all the pipes and probably gonna run it stock, low boost for a while. Thanks
Removing the vanes will kill any chance of that engine spooling it. The solenoid is pulse width controlled, and from my research positioning is determined by amperage.
There are much easier VGTs out there, the Dodge one has an arm under the controller you can put an actuator on.
If you want to spend the money for controller great, it would have to be a customer controller noone makes them any more. If you google many people have asked about it, theirs a cummins somewhere with a 6.0 turbo on it, custom controller he used he had drive ability issues with turbo surge and he said it was a programming issue. And if you take out the vanes it will end up super laggy, since the vanes dont actually open all the way anyways, something like 90%, good news is thou that put it in and unpluggged 6.0 turbo is suppose to default to no vgt so max exhaust flow so lots of top end with poopy bottom end. The solenoid from the research I did, is suppose to run on 12 volts, but I have not being able to confirm this. The vanes coke up so clean the vanes while its out. And to check the solenoid for the vgt it should be 3.42-4.18 ohms at 73 Fahrenheit and 4.4-5.3 at 200 Fahrenheit. It dosn't take a lot of power to run the solenoid either 2.26-3.5 amps at 12 volts and if it run on 5 volts its even less 1.46 -.94 amps. I have though about it too. Just take lots of pictures it would be definitely be interesting if you do.
Ok, so basically, my budget is as little as possible as I am in college, so a fancy controller is out of the picture. If I had the turbo all plumbed up with the vanes all in it, could I place them in a certain position and drive it like that? Like, I could make them so they are somewhat in between open and closed. That way I could play around with it to find a powerband that works for me and keep it there possibly. Just leaving the electronic controls out of it?
Haha I'm a little slow upstairs so that's why I'm thinkin of all these bad ways to do stuff. By 0% vgt you mean that it would just be fully open, or 90%, right? If so, do you think I could use it like that or would I have to be doin 3k all the time to see any benefits?
Unplugged 0% vgt full flow. In 6.0 the vanes do not open all the way if you google around theirs manual with chart that explains their operation and it says how much. Lots of 6.0 guys unplug them so they roll more coal.
Ok, thanks. I'll probably try it and see what happens. Its gonna take me a long time because I'm pretty bad at welding, but it should be cool even if it is laggy. I'm gonna use the factory y-pipe, but cut it off early and make an up pipe from there. The passenger manifold will connect to it in a y with a single pipe going to the turbo. I'm gonna see if I can cram it in the factory place, but it might be too big for there, without a cowl hood, that is.
91dirtydiesel has a vgt, not sure if it's 6.0 or not, but he controls it with a **** on the dash. Search around and see if you can find some good info from him.
Thanks, I know his is from a 6.7 Cummins so it is mechanically actuated by a spring thats opens up more as pressure comes. Its a different design of a vgt, but seems to work well. I've read a lot about his build
idisam6.9 here is a good thread for you to read, this a guy who put 6.0 turbo on a 12 valve. He drove it for awhile and some fine tuning it when his truck stolen. Still a good read.
